+### Importing SmartArchive
 
-For further information read the linked docs at the top of this readme.
+First, import `SmartArchive` from `@push.rocks/smartarchive` using ESM syntax:
 
-## Legal
+```typescript
-> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc)
+import { SmartArchive } from '@push.rocks/smartarchive';
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+```
+
+### Extracting Archive Files
+
+You can extract archive files from different sources using `SmartArchive.fromArchiveUrl`, `SmartArchive.fromArchiveFile`, and `SmartArchive.fromArchiveStream`. Here's an example of extracting an archive from a URL:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function extractArchiveFromURL() {
+  const url = 'https://example.com/archive.zip';
+  const targetDir = '/path/to/extract';
+
+  const archive = await SmartArchive.fromArchiveUrl(url);
+  await archive.exportToFs(targetDir);
+
+  console.log('Archive extracted successfully.');
+}
+
+extractArchiveFromURL();
+```
+
+### Extracting an Archive from a File
+
+Similarly, you can extract an archive from a local file:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function extractArchiveFromFile() {
+  const filePath = '/path/to/archive.zip';
+  const targetDir = '/path/to/extract';
+
+  const archive = await SmartArchive.fromArchiveFile(filePath);
+  await archive.exportToFs(targetDir);
+
+  console.log('Archive extracted successfully.');
+}
+
+extractArchiveFromFile();
+```
+
+### Stream-Based Extraction
+
+For larger files, you might prefer a streaming approach to prevent high memory consumption. Here’s an example:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+import { createReadStream } from 'fs';
+
+async function extractArchiveUsingStream() {
+  const archiveStream = createReadStream('/path/to/archive.zip');
+  const archive = await SmartArchive.fromArchiveStream(archiveStream);
+  const extractionStream = await archive.exportToStreamOfStreamFiles();
+  
+  extractionStream.pipe(createWriteStream('/path/to/destination'));
+}
+
+extractArchiveUsingStream();
+```
+
+### Analyzing Archive Files
+
+Sometimes, you may need to inspect the contents of an archive before extracting it. The following example shows how to analyze an archive:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function analyzeArchive() {
+  const filePath = '/path/to/archive.zip';
+  
+  const archive = await SmartArchive.fromArchiveFile(filePath);
+  const analysisResult = await archive.analyzeContent();
+  
+  console.log(analysisResult); // Outputs details about the archive content
+}
+
+analyzeArchive();
+```
+
+### Creating Archive Files
+
+Creating an archive file is straightforward. Here we demonstrate creating a tar.gz archive:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function createTarGzArchive() {
+  const archive = new SmartArchive();
+  
+  // Add directories and files
+  archive.addedDirectories.push('/path/to/directory1');
+  archive.addedFiles.push('/path/to/file1.txt');
+  
+  // Export as tar.gz
+  const tarGzStream = await archive.exportToTarGzStream();
+  
+  // Save to filesystem or handle as needed
+  tarGzStream.pipe(createWriteStream('/path/to/destination.tar.gz'));
+}
+
+createTarGzArchive();
+```
+
+### Stream Operations
+
+Here's an example of using `smartarchive`'s streaming capabilities:
+
+```typescript
+import { createReadStream, createWriteStream } from 'fs';
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function extractArchiveUsingStreams() {
+  const archiveStream = createReadStream('/path/to/archive.zip');
+  const archive = await SmartArchive.fromArchiveStream(archiveStream);
+  const extractionStream = await archive.exportToStreamOfStreamFiles();
+  
+  extractionStream.pipe(createWriteStream('/path/to/extracted'));
+}
+
+extractArchiveUsingStreams();
+```
+
+### Advanced Decompression Usage
+
+`smartarchive` supports multiple compression formats. It also provides detailed control over the decompression processes:
+
+- For ZIP files, `ZipTools` handles decompression using the `fflate` library.
+- For TAR files, `TarTools` uses `tar-stream`.
+- For GZIP files, `GzipTools` provides a `CompressGunzipTransform` and `DecompressGunzipTransform`.
+- For BZIP2 files, `Bzip2Tools` utilizes custom streaming decompression.
+
+Example: Working with a GZIP-compressed archive:
+
+```typescript
+import { createReadStream, createWriteStream } from 'fs';
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function decompressGzipArchive() {
+  const filePath = '/path/to/archive.gz';
+  const targetDir = '/path/to/extract';
+
+  const archive = await SmartArchive.fromArchiveFile(filePath);
+  await archive.exportToFs(targetDir);
+
+  console.log('GZIP archive decompressed successfully.');
+}
+
+decompressGzipArchive();
+```
+
+### Advancing with Custom Decompression Streams
+
+You can inject custom decompression streams where needed:
+
+```typescript
+import { createReadStream, createWriteStream } from 'fs';
+import { SmartArchive, GzipTools } from '@push.rocks/smartarchive';
+
+async function customDecompression() {
+  const filePath = '/path/to/archive.gz';
+  const targetDir = '/path/to/extract';
+
+  const archive = await SmartArchive.fromArchiveFile(filePath);
+  const gzipTools = new GzipTools();
+  const decompressionStream = gzipTools.getDecompressionStream();
+
+  const archiveStream = await archive.getArchiveStream();
+  archiveStream.pipe(decompressionStream).pipe(createWriteStream(targetDir));
+
+  console.log('Custom GZIP decompression successful.');
+}
+
+customDecompression();
+```
+
+### Custom Pack and Unpack Tar
+
+When dealing with tar archives, you may need to perform custom packing and unpacking:
+
+```typescript
+import { SmartArchive, TarTools } from '@push.rocks/smartarchive';
+import { createWriteStream } from 'fs';
+
+async function customTarOperations() {
+  const tarTools = new TarTools();
+
+  // Packing a directory into a tar stream
+  const packStream = await tarTools.packDirectory('/path/to/directory');
+  packStream.pipe(createWriteStream('/path/to/archive.tar'));
+
+  // Extracting files from a tar stream
+  const extractStream = tarTools.getDecompressionStream();
+  createReadStream('/path/to/archive.tar').pipe(extractStream).on('entry', (header, stream, next) => {
+    const writeStream = createWriteStream(`/path/to/extract/${header.name}`);
+    stream.pipe(writeStream);
+    stream.on('end', next);
+  });
+}
+
+customTarOperations();
+```
+
+### Extract and Analyze All-in-One
+
+To extract and simultaneously analyze archive content:
+
+```typescript
+import { createReadStream, createWriteStream } from 'fs';
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+async function extractAndAnalyze() {
+  const filePath = '/path/to/archive.zip';
+  const targetDir = '/path/to/extract';
+
+  const archive = await SmartArchive.fromArchiveFile(filePath);
+  const analyzedStream = archive.archiveAnalyzer.getAnalyzedStream();
+  const extractionStream = await archive.exportToStreamOfStreamFiles();
+
+  analyzedStream.pipe(extractionStream).pipe(createWriteStream(targetDir));
+
+  analyzedStream.on('data', (chunk) => {
+    console.log(JSON.stringify(chunk, null, 2));
+  });
+}
+
+extractAndAnalyze();
+```
